What is FRCM?
Repair, protect and strengthen aging, damaged or overloaded concrete and masonry structures in one application and significantly reduce your installed cost.
FRCM or Fabric-Reinforced Cementitious Matrix combines high-performance sprayable mortar with a carbon-fiber grid to create thin-walled, reinforced concrete shells without adding significant weight or mass to the structure.
Benefits
- Repair and strengthen structures using only a thin layer of material
- Can be applied in multiple grid layers (four maximum) to achieve desired strengthening – ½”-1” (12.7-25.4 mm) thick for one-layer grid applications, adding ½” (12.7 mm) for each additional grid layer
- Lightweight system for vertical surfaces and overhead applications
- Suitable for harsh environments or service conditions including marine locations, elevated temperatures, humidity, abrasion and UV
- Works on damp substrates
- Installation process is similar to that for wet shotcrete repair mortars
- Quick installation with less preparation than traditional shotcrete repairs with rebar
- Does not create a vapor barrier
- Matches substrate finish
- 100% solids formulation
- Carbon-fiber grid features excellent chemical and corrosion resistance
- Non-hazardous shipping
